These backpacks are meant for fast paced outdoors events. Hydration packs are all the craze because they help us keep ourselves in excellent condition the entire time we're outside. You're going to sweat and you'll feel the heat from all that intense exercise but you can keep yourself from tiring out with these hydration packs.

The Rim Runner and Fourteener are lightweight and conveniently designed for people who want to enjoy their time outside. Buy the Rim Runner if you need more compartments for your stuff, but if you value space you might want the Fourteener instead.
